ATRRS Class Dates 2021

The ATRRS (Army Training Resources and Requirements System) displays the available class dates and the seat allocations for each class. To be able to see the class dates for 2021, you must log in. If you haven’t registered yet, you can use your AKO (Army Knowledge Online) to register but there is a lot more that goes into registering to ATRRS than just AKO.

First and foremost, to even begin with seeing available classes, you must have filed a Form 2875. Once that is done, there is the DD Form 2929 which works as a follow-up to Form 2875. After that, you will need to fax it. From there on, it’s a waiting game for about two to three weeks. Although this can take less time, this is how long it usually takes. Whether you wait for a longer or a shorter period of time, you will be able to register with the new user information. Learn more about how the registering process works from here.

Keep in mind the civil workers of the Army can also join certain courses. Generally, it is a lot faster for civilian employees of the Department of Defense to obtain a login to the ATRRS. This is merely because there aren’t many that go into their profile. As a service member, your information is processed a lot more comprehensively.

As for the actual 2021 class dates, you can browse and see the open classes for future dates by sorting the training classes by date. One thing to know about this is not all classes are scheduled. So you may need to wait a couple of months to see certain classes which will take place in 2021.
